您如何看待这种构图?这是错的吗?怎么做得好?
$graph_url = 'https://graph.facebook.com/me?access_token=' . $result['access_token'];
$fb_user = json_decode( file_get_contents( $graph_url ) );
try {
$user = new Model_User( $fb_user->username );
$user_meta = new Model_User_Meta ( $user->get ( 'user_id' ) );
$user_meta->set_user_meta( '_facebook_id', $fb_user->id );
$user_meta->set_user_meta( '_last_logged_in', 'current_timestamp' );
$user_meta->save();
} catch ( Exception $e ) {
if ( $e->getCode() === 0 ){
$password = Helper_Password::generate_password();
$hash = Helper_Password::hash_string( $password );
try {
$user = new Model_User();
$user->set( 'user_name', $fb_user->username );
$user->set( 'user_pass', $hash );
$user->set( 'user_email', $fb_user->email );
$user->set( 'user_status',( $fb_user->verified ? 'active' : 'inactive' ) );
$user->set( 'display_name', $fb_user->name );
$status = $user->save();
$user_meta = new Model_User_Meta ( $status->user_id );
$user_meta->set_user_meta( '_facebook_id', $fb_user->id );
$user_meta->set_user_meta( '_last_logged_in', 'current_timestamp' );
$user_meta->save();
} catch ( Exception $e ) {
throw $e;
}
} else {
throw $e;
}
}

尝试在捕获期间恢复,然后在必要时抛出异常就可以了。
但是你的代码中存在一些含糊之处。你指的是哪个$e
?原来的例外,还是新的例外?如果要抛出原始异常,则不应在第二个catch语句中覆盖$e
:
} catch ( Exception $e ) {
if ( $e->getCode() === 0 ){
try {
// try recovering here?
} catch ( Exception $otherException ) {
throw $e; // throw the original exception instead of the new one
}
} else {
throw $e;
}
}
如果你想抛出新的异常,你根本不需要内部捕获......
} catch ( Exception $e ) {
if ( $e->getCode() === 0 ){
// try recovering here, and let the exception fly as they will
} else {
throw $e;
}
}
